I'm currently running Win10 on the VM. Now a little over a month ago? there was the Win10 Creators Update which broke the ability to save files due to the way MS changed how files were being saved. However, vmware updated the tools later and that took care of the issue.
Then within the past week we had Apple provide the 10.13.2 Supplemental update due to a security issue with the Fusion 10.1.1 update right on its heels. Since that point in time, I ran into issues with everything freezing (had to do a hard reboot), not waking up (had to do a hard reboot), or stepping away for an hour or more and return to a sign in screen due to a kernel panic and reboot.
Got to the point in the last few days that I really could not get anything done.
Today I bit the bullet and backed everything up and reinstalled HighSierra. Next step will be a fresh install of everything (*shudders*).
